Glycogen storage disease due to muscle and heart glycogen synthase deficiency

GYS1 · rs751382433

Strength of the evidence

There is no record yet to score this position by (a ClinVar disease classification or a genome-wide significant study). That is not the same as weak evidence.

How this is scored

4: ClinVar disease-causing, reviewed by an expert panel or a guideline (3–4 stars). 3: ClinVar, several labs agreeing (2 stars), or a genetic study at p ≤ 10−50. 2: ClinVar from one lab (1 star), or p ≤ 10−20. 1: ClinVar submitted without criteria (0 stars), or genome-wide significance (p ≤ 5×10−8). The higher of the two counts. It says how solid the evidence is, not whether it matters for a particular person.

What ClinVar records

Classification Conflicting classifications of pathogenicity for Glycogen storage disease due to muscle and heart glycogen synthase deficiency; criteria provided, conflicting classifications (1 of 4 stars, 2 submitters), last evaluated 2024-06-25.

Change history MyGeneLog™ keeps a copy of every weekly release from 2026-10-19 and compares them. This position's classification has not changed since.

What this is ClinVar's aggregate record for this position (as of its 2026-10-19 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.

What each result means

A/A Two copies of the version labs disagree about for Glycogen storage disease due to muscle and heart glycogen synthase deficiency: in ClinVar, some labs call it disease-causing and others do not. A result like this should be confirmed by a medical genetic test and talked through with a doctor; consumer DNA files can misread rare variants. (ClinVar VCV000893347, criteria provided, conflicting classifications)
A/G One copy of the version labs disagree about for Glycogen storage disease due to muscle and heart glycogen synthase deficiency: in ClinVar, some labs call it disease-causing and others do not, so what one copy means is not settled. A genetic counsellor can look at the separate records. (ClinVar VCV000893347, criteria provided, conflicting classifications)
G/G No copy of the version labs disagree about for Glycogen storage disease due to muscle and heart glycogen synthase deficiency: in ClinVar, some labs call it disease-causing and others do not. This is the usual result. (ClinVar VCV000893347, criteria provided, conflicting classifications)

Questions about rs751382433

What is rs751382433?

rs751382433 is a single position in the genome, in or near the GYS1 gene. Published research associates it with glycogen storage disease due to muscle and heart glycogen synthase deficiency. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs751382433 mean I will get this?

No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.

Where does the information about rs751382433 come from?

ClinVar VCV000893347, criteria provided, conflicting classifications. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
